What if my gold status expires during platinum challenge

I have a question regarding platinum challenge. My gold status will be expired at the end of January, 2019. If I start platinum challenge in December, 2018 and finish in February, 2019, will I have a platinum status until February, 2020?

Thank you for your request. You do not need to finish your challenge before your status downgrades. You will be Elite Silver after your Elite Gold status expires and still enrolled in the challenge. When you complete the challenge you will automatically be upgraded to Elite Platinum. If you do not complete the challenge then you will stay Elite Silver.

According to the current rules of a Status Challenge, If you are approved for a Platinum status challenge that starts in December of 2018 you get three months until March of 2019. If you finish by March 2019 or early in February 2019 as mentioned, you will then be Platinum Elite until February of 2021.
